A mobile phone is a mobile phone. But can you combine(联合) the two to do something for your local environment? It may be possible. When you have finished with your mobile phone, you will be able to bury(埋) it in the garden or a plant pot and wait for it to flower. A biodegradable(生物可降解的) mobile phone was introduced by scientists. It is hoped that the new type of phone will encourage people to recycle. Scientists have thought of a new material over the last five years. It looks like any other plastic, but overtime it can break down into the soil without giving out any poisonous chemicals(有毒的化学物质). British researchers used the new material to develop a phone cover with a sunflower seed(种子). When this cover changes into waste, it forms nitrates(硝酸盐). These feed the seed and help the flower grow. “We have only put sunflower seeds into the cover so far. But were trying to find out which flowers would perform best. Maybe we could put roses in next time,” said one scientist.As phone technology is developing so quickly, people are always throwing their mobile phones away. This means producers are under pressure(压力) to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal(金属) and chemical waste to the environment. A biodegradable cover can reduce the harm to nature, according to the scientists. “The seed is released(释放) and the flower grows in the pot, so you dont have to worry about the phone when you have finished using it,” said Kerry Kirwan, the leader of the research team, which is based at the University of Warwick in Britain. 36.Scientists did this type of research about biodegradable mobile phones in order to .()A.make the mobile phones more beautifulB.encourage people to recycleC.find a new way to grow flowersD.produce more mobile phones37.Millions of mobile phones have been sold this year and people will within two years.()A.bury most of them in the gardenB.put sunflower seeds into most of themC.take out their coversD.throw most of them away38.What does the underlined phrase “break down” mean?()A.change into chemicalsB.not workC.be dividedD.break out39.We can infer(推断) from the passage that .()A.the new type of mobile phones is already on the marketB.some 650 million mobile phones have been sold within two yearsC.British scientists are doing the researchD.roses perform best in this type of mobile phones40.Whats the best title for the passage?()A.the Harm to NatureB.the Developing Phone TechnologyC.Phones and FlowersD.Mobile Phones and Environment【参考答案】.1.C2.Aallow sb. to do sth.意为“允许某人做某事”。故选A。3.A4.B根据下一句“开着灯我睡不好”可知,前句表示“关灯”,故选B。5.B6.B7.B8.D根据“We should make good use of it.”可知:用run out表示“石油总有一天会用完”。故选D。9.D10.D.11.wisely12.punished13.steps14.harmful15.digging16.simply17.living18.powerful19.carelessly20.seriously.2125ACABD2630CBCCB3135ADDAB.主旨大意本文是一篇说明文。文章主要介绍了科学家们研究出来一种可降解的新型手机。3640BDACD
